Specification of Letters Patent.

Patented Oct. 20, 1914.

Application filed March 28, 1914. Serial No. 827,849.

To all whom it may concern:

Be it known that I, HUBERT DALTON, a

citizen of the United States of America, and

resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in ShaftHangers, of which the following isa specification. i

This invention relates broadly to improvements in power-transmitting apparatus, and

more particularly concerns itself with the provision of means of the above general type adapted for advantageous employment in connection with the transmission of comfrom the operation of a foot-treadle.

One of the objects thereof is to provide a simple and practical hollow columnar housing for an operative interconnection between what may be termed the driving and the driven members. i v

A collateral object is to combine in the same housing an interior chamber for the accommodation of said interconnection, a supporting pillar for carrying thereon the working parts to be actuated by or through said driven member, and a sui'ficientlyfixed and rigid support for a hanger or support ing means for said driven member.

Another object is to provide a unitary structure in the nature of a hanger, prefer} ably of such a type that thesame may be cast as one part, adapted to support a revoluble shaft to carry said driven member, and also adapted to support in addition if desired means capacitated frictionlessly to carry the shaft for revolution relatively of the hanger,characterized in this that said hanger as cast will not require an extensive amount of machining and in this also that a relatively small amount of metal is used for the upbuilding of said hanger.

Another object is so to conform said hanger and its supported parts that they may be entirely assembled as a combination complete in itself, before mounting the h anger permanently in position. i a

Another object is to provide a general sup porting and power transmlttlng structure for utilization in connection with machinery of any type, which shall have as marked advantages the presence of an exceedmgly small number of parts, great slmpliclty of construction, extreme inexpensiveness as to the producing cost of each of said parts, and rigidity, rellablllty and sturdlness of construction, as well as accessibility of the moving parts for repairs, oiling, adjustment, at-

tachment and removal, not attained heretcr fore.

Other objects and aims of the invention, more, or less broad than those stated above, together with the advantages inherent, will be 1n part obvious and in part specifically referred to in the course of the following description of the elements, combinations, arrangements of parts, and applications of principles constituting the invention; and the scope of protection contemplated will appear from the claims. paratively small power, asthat generated In the accompanying drawing, which is to be taken as apart of this specification, I and in which I have shownone of the various possible embodiments of the invention as at present preferred, Figure 1 is a side elevation, partially broken away andpar-- tially 1n sectlon, showing a preferred embodnnent of the mvention; Flg. 2 1s a front elevation, partially broken away and parlar partsthroughout the several views of thedrawing.

Referring now particularly to the construction shown in the drawing, 5 represents a hollow vertical column which may support uponthe integral upper or table-leaf 6 thereof a base-board or supporting table 7 (indicated in broken-lines) adapted to carry a suitable burden, as the'bedplate or feet of a lathe or other machine, or said column may directly support said lathe or other" machine. Column Sat its lower endcarries an integral foot-plate 8, preferablyof suflicient. dimenslons to capacitate the column singly to support the lathe or other selected.

superstructure. And it is this column 5 which here directly supports the hanger 9. The hanger when mounted in place partially extends into the chamber 10 within the column and partially projects exteriorly of the latter; a vertical wall of the column being provided with an opening 11 and bosses 11" with which said hanger is associated as shown and as hereinafter described. Hanger 9 conslsts of a unitary casting conformed as shown, provided with a longitudinal bore 12 which throughout its length is of a diameter preferably greater than the diameter of the shaft associated therewith. The hanger, intermediately of its length, is provided with an integral flange-plate 13, preferably of a substantially elliptical form as shown in Figs. 1 and 3, adapted to permit of said flange-plate being placed overlapping of opening 11 and of the anchoring of the hanger in position upon the column 5; the bolts 14 being present for the latter purpose. It will be seen immediately that the hanger is of an exceedingly simple and sturdy construction, consisting primarily of said flange-plate 13, a tubular casing 15 (for establishing the bore 12 and the recess 16), an annular member 17 carrying a recess 18, and the two T-struts 19 (see Fig. 3) which serve to mount the annular member 17 upon and space the same predeterminedly away from said flange-plate.

Mounted in each of the recesses 16 and 19,

as indicated in broken-lines in Fig. 2, and.

as shown in enlarged detail in Fig. 4, is a ball-bearing device of a well-known commercial type. These devices in themselves form no part of the subject matter of the present invention. Each of the devices includes a shaft-contacting ring, 20, a co6perant ring 21, a ball-race established between the rings, a plurality of balls 22 movable in said race, and an annular containing shell 23. The devices are maintained in their respective recesses preferably by means merely of a suction or press fit. Shaft 24: is revolubly mounted within the hanger as shown, and preferably is closely gripped by the rings 2O.

A pulley 25,3vhich has hereinbefore been referred to as the driven member, is fixedly carried by the shaft, the screw 26 being present for the purpose. The shaft also fixedly carries a cranlearm 27. The crank-arm is provided with an off-set stud 29 upon which is pivotally mounted one terminus of a pitman 28, the other end thereof being adjustably and rigidly coupled, as by means of the nut 28, with a bifurcated link-member 30 pivotally attached to the treadle 31 as indicated. Treadle 31 is itself pivotally mounted within a trunnion extension 32 cast integrally with the housing. 5; the footplate of the treadle projecting from the housing by way of the opening 33. The iousing is also provided with a swinging door 34: which may be opened to expose a suitableopening in the housing, thus to ob- .tain convenient access to the interior of chamber 10 for repairs, oiling, adjustment, attachment and removal of any of the parts located interiorly of the chamber. A belt may of-course be suitably associated with pulley 25 and extend upwardly to transmit power from said pulley to a cone-pulley or the. like forming a part of the particular parts, and, next, mounting said hanger upon 1 the housing and coupling up the pitman 28. The hanger 9, if constructed as a casting, ,1 is preferably given no machining whatever except perhaps a subjection to a reamer or 1 drill-press to true up the recesses 16 and 18. y The ball-bearing devices are then inserted in 1 these recesses, the shaft 2a is arranged longi- Ftudinally of the hanger, and pulley 25 is I fixedly attached to the shaft at such a point longitudinally thereof as to predetermine a proper protrusion from the hanger of the opposite terminus of the shaft, upon which terminus crank-arm 27 is then fixedly mounted. The pulley and the crank-arm as thus associated will cooperate to prevent longitudinal shifting of the shaft relatively of its hanger and also to prevent any accidental displacement of the ball-bearing devices. The collection of parts so assembled into one complete operative unit are ready for permanent support upon the housing. And at this point attention may be called to the substantially elliptical opening 11 and to the characteristic construction of that portion of the hanger which in Fig. 2 is disclosed as located rightwardly of flange- ;plate 13. For it 1s of great practical advantage to construct the housing 5 with horizontal dimensions one of which (such as that indicated by the double-pointed arrow 35 shown in Fig. 1) shall be considerably less than another of which (as indicated by the double-pointed arrow 36 of Fig. 2). Now the opening 11 is preferably formed in one of the narrower of the two sets of vertical walls which partially establish the housing. Yet the opening must be so conformed that there may be inserted therethrough for accommodation within the chamber 10 not only the portion of the hanger 9 which supports the annular member 17 but also the crank-arm 27 and at the same time the last-mentioned portion of the hanger must be, whatever the exigencies of its cross-section design, as strong and rigid as if of a hollow cylindrical type. In this connection, attention is called to the important feature which resides in the fact that as aforesaid merely the T-struts 19 serve to mount the annular member 17 upon and spaced predeterminedly away from flange-plate 13, the result being that this portion of the hanger is exceedingly sturdy and yet is possessed of what may be termed an elliptical composite cross-section the minor axis of which is substantially coinci dent with the minor axis of opening 11 and the major axis of which is substantially coincident with the major axis of said opening. Attention is called to thefact, too, that by means of the bolts 14 (and here attention,

maybe called to the fact that neither the flange-plate nor the portion of the housing which surrounds the; opening 11 need .be

given any machining), the pitman 28 is inserted within chamber 10 and is suitably pivotally connected with stud 29. The treadle 31, having been preferably inserted through the opening 33, is properly mounted in the trunnion-extension 32; and the lower end of the pitman is adjustedand rigidly connected to the link-member 30. f

It will thus be seen that I have provided an embodiment of the invention well calcu-v lated to attain the various ends and objects thereof, and an embodiment, moreover, that is exceedingly practical, reliableof operation and convenient and economical of shopspace. While the embodiment disclosedis of the foot-power type, it is obvious that a motor could directly drive the shaft 24 or otherwise be suitably coupled therewith, the motor in either event being completely located interiorly of the housing, and an additional door or doors beingprovided if de sired for access thereto.

Inasmuch as many changes could be made in the above construction, and many apparently widely different embodiments of my invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in the following claims is intended to cover all the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
